I am also getting ready to order solder for my new wave. Based on what I have read (here and other places) people prefer Sn100c for the wave. I have yet to hear of someone using Sn100c and switching to SACx. I am using SAC305 for reflow and I am tryi

Good afternoon. From what it sounds like is that the solder joins are not getting hot enough or if it Au, then the increase in the Au content of the joint is increasing the melting point of the final solder joint. To some extent, this will also hap

Hi Pavel, Real Chunks, Thanks for your valuable inputs..Selecting the correct location for board profiling is critical in determining the solder joint quality. Am I right to say TC wire attachment locations priority should be as below: (1) Thermal

ECD sells the MOLE, and they sell both the Oven Rider and the Wave Rider to accompany it. The thing is, you can profile both an oven and a wave machine without either if you're willing to just solder your thermocouples to a board. The nice thing ab

We have been having problems with proper wetting when running mainly lead free but also leaded solder in our Ersa Hotflow 3. Solder either often looks grainy or doesn't flow over the whole pad. This is generally the case when my profile is 170 firs

White solder mask does have a tendency to yellow within the lead free environment. so double coating will not help any. I due believe the flux is a factor in the yellowing but due to the color is the main reason. Find out what brand of S/M mask they

After looking at your profile, some general thoughts.... Your profile looks like what is commonly called a ramp-spike profile and not a ramp-soak-spike profile. Going off of Sarason's comment, you may not have a good soak period before the spike in

Hello Dave, Before I get into waste management, I must first stress the importance of checking with your local regulating agencies. Every area can be and usually is different. California regulations differ from Ohio and Ohio�s are different than Mu

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe
